What data for this category looks like
Data sources for this category include terminal management platforms, asset systems, user trouble reporting channels, and software repositories. Teams process daily documents including terminal trouble tickets, installation manifests, software installation records, and remote assistance records. Two categories of data update rhythms exist: daily batch synchronization and real-time request triggering. Data fields include terminal asset numbers, trouble classification, processing duration, software version numbers, and trouble reporting timestamps. Document structures vary across sources, and teams must perform cross-system mapping and matching for some fields.
Constraints on database and operations workflows
Decentralized data sources require teams to configure synchronization permissions for multiple data sources to avoid data silos. Differences in update rhythms require the database to support both batch writes and real-time request processing. Flexible document structures require the database to support flexible field mapping rules to adapt to document formats from different sources. Critical identifiers such as terminal asset numbers require teams to create corresponding indexes to improve retrieval efficiency. Data errors can lead to employee downtime and work order backlogs, so teams must configure data verification and backup mechanisms to ensure data security.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
MONGODB_URI | mongodb://fastgpt:securepass@192.168.1.100:27017/terminal_support?authSource=admin | Stores unstructured remote assistance records and semi-structured trouble ticket data, and complies with FastGPT v4.17.0 storage specifications |
PG_URL | postgresql://fastgpt:securepass@192.168.1.100:5432/terminal_assets | Stores structured asset data such as installation manifests and software installation records |
DB_MAX_LINK | 80–120 | Adapts to the concurrent volume of daily batch writes and real-time requests, and prevents database connection exhaustion |
REDIS_URL | redis://:securepass@192.168.1.100:6379/0 | Caches frequently retrieved terminal asset numbers and trouble type index data to reduce database query latency |
| Data synchronization frequency | Daily batch synchronization and real-time request triggering | Matches the update rhythm of terminal data, balancing storage efficiency and real-time performance |
| Data backup cycle | Every 24 hours | Prevents loss of terminal trouble tickets and asset data, and aligns with business risk levels |
Three common configuration errors
- Symptom: Teams cannot retrieve terminal trouble ticket data after writing it, and logs show MongoDB connection authentication failure. Cause: Teams fail to correctly configure the authentication source and username parameters in
MONGODB_URI, preventing database connection establishment. - Symptom: Teams encounter field mismatch errors when batch importing installation manifests. Cause: Teams fail to configure the database schema mapping rules corresponding to
PG_URL, preventing structured data from being written correctly. - Symptom: Real-time updates of remote assistance records have higher latency than expected. Cause: Teams fail to adjust the
DB_MAX_LINKparameter to a reasonable range, leading to database connection exhaustion and inability to process real-time requests.
How to verify successful configuration
- Run write tests for a single terminal trouble ticket and a batch of installation manifests to confirm data is correctly stored in the corresponding databases.
- Check the active connection count of the database connection pool to confirm it does not exceed the
DB_MAX_LINKconfiguration value. - Trigger a real-time remote assistance record update request to confirm data update frequency matches the configured synchronization rules.
- Check that database backup files generate normally according to the configured backup cycle.
